It might have been supposed that as the Romans had suffered so much from the pirates, and as Rome itself was dependent for subsistence on foreign supplies of corn, which could not be regularly obtained, while the pirates were masters of the seas, they would have directed their attention more than they did to maritime affairs and commerce, especially after the experience they had had of the public calamities which might thus be averted. This, however, was not the case, even after the war against the pirates, which was so successfully terminated by Pompey; for Pompey's son, who opposed the triumvirate, by leaguing with the pirates, (of what nation we are not informed,) repeatedly, during his warfare, reduced the city of Rome to great straits for want of corn. As the operations by sea which he carried on, in conjunction with the pirates, are the last recorded in history, by means of which Rome was reduced to such straits, and as this repeated proof of the absolute necessity of rendering her independent of any maritime power for supplies of corn, seems to have been the chief inducement with Augustus to establish regular and powerful corn fleets, we shall notice them in this place, though rather posterior to the period of Roman history at which we have arrived. The younger Pompey, it would appear, was sensible that his father's fame and fortune had been first established by his success at sea: this induced him to apply himself to maritime affairs, and, when he resolved to oppose the triumvirate, to trust principally to his experience and force by sea, to oblige them to comply with his terms. Accordingly, he built several ships, some of which are said to have been covered with leather: he associated himself with all the pirates he could meet with; and, when sufficiently powerful, he took possession of Sardinia, Sicily, and Corcyra, made himself master of the whole Mediterranean sea, and intercepted all the convoys which were carrying provisions and other necessaries to Rome. The occupation of Sicily enabled him to prevent any corn from being shipped from that island, and to intercept all that came from the eastern ports of the Mediterranean. His possession of Sardinia and Corcyra enabled him to intercept all that came from the west, while he captured all that came from Africa by his squadrons, which were constantly cruising in that direction.
